The eternal resource locator: an alternative means of establishing trust on the world wide web
Ross Anderson, Václav Matyáš, Fabien A. P. Petitcolas · 1998
Much research on Internet security has concentrated on generic mechanisms such as firewalls, IP authentication and protocols for large scale key distribution. However, once we start to look at specific applications, some quite different requirements appear. We set out to build an infrastructure that would support the reliable electronic distribution of books on which doctors depend when making diagnostic and treatment decisions, such as care protocols, drug formularies and government notices. The integrity, authenticity and timeliness of this information is important for both safety and medico-legal purposes. We initially tried to implement a signature hierarchy based on X.509 but found that this had anumber of shortcomings. We therefore developed an alternative means of managing trust in electronic publishing. This has a number of advantages whichmay commend it in other applications. It does not use export-controlled cryptography; it uses much less computation than digital signature mecha...
